For a linear plot of \(\log(x/m)\) versus \(\log p\) in a Freundlich adsorption isotherm, which of the following statements is correct ? (k and n are constants)
Show Hint
- Both k and 1/n appear in the slope term.
- 1/n appears as the intercept.
- Only 1/n appears as the slope
- \(\log(1/n)\) appears as the intercept.
The Correct Option is C
Solution and Explanation
Taking logs: \(\log\dfrac{x}{m} = \log k + \dfrac{1}{n}\log p\).
This is a straight line with \(y = \log(x/m)\) and \(X = \log p\).
Slope = \(1/n\) only; intercept = \(\log k\).
Hence only 1/n appears as the slope.
Answer: (3) Only 1/n appears as the slope

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
